, Geo eWFuZI/ BY 7 Patented June 15, 1954 UNITED STATES PATENT OFFICE 2,681,254 PLURAL SPRAY SHOWER HEAD George W. Fuller, Downey, Calif. Application October 29, 1951, Serial No. 253,602

2 Claims.

This invention relates to plural spray shower heads, and more particularly to a plural spray shower head in which diirerent spray nozzles, in the nature of inserts, are connected with said head in such a way that the sprays discharged therefrom overlap each other as they leave the head and the spray nozzles in such a way as to produce a more eiTective shower.

Among the salient objects of the invention are: to provide a shower head of the character referred to which can be connected with the usual water supply pipe or arm, with a ball joint for adjustment, whereby it is easy to adjust to any desired angle; to provide a shower head or body with a chambertherein into which water from said supply pipe is discharged and from which it overflows into the different spray nozzles inserted therein, with provision for trapping any solid particles which might be carried into said shower head; to provide a spray nozzle which can be inserted into a shower head and which is self-contained and which has as a part thereof a yieldingly held spray plug which can be easily pressed i11- wardly by the finger for the purpose of freeing any particles which might lodge in the discharge passageway or discharge outlet; to provide an insert spray nozzle having a cylindrical inner portion which extends up into the shower head and over into which the Water flows from the chamber of the shower head, the end of said cylindrical portion being contiguous to the top of the shower head chamber, whereby to form a restricted inflow for water and thus also form a trap for pre venting particles from flowing into the spray nozzle; to provide in combination with such a spray nozzle a conical-like outlet therefrom, forming a restricted discharge opening therefrom with a spray plug having a body portion to seat in said spray nozzle and leave for water therearound, and which head portion positioned in the discharge opening from said spray nozzle to cause a jet-like discharge therefrom.

Other objects and advantages of the invention will appear from the following more detailed description thereof, taken with the accompanying sheet of drawings, in which:

Figure 1 is a side elevation of a shower head embodying my invention;

Figure 2 is a bottom plan view thereof;

Figure 3 is a vertical sectional view, taken on the line 3-3, of Fig. 2;

Figure 4 is a perspective view of a spray plug;

Figure 5 is an enlarged vertical sectional view of one of the insert spray nozzles; and

2 Figure 6 is a horizontal sectional view, taken on line 6-6, on Fig. 5. Referring in detail to Said insert nozzle members, one of which is shown in section in Fig. 5, have skirt portions, as

threaded, as at ed openings l 3, a conical-like outlet 29, said l8, to screw into one of the threadsaid restricted formation providing floor, as at 19, with the restricted insert having the cyindrical porinto the chamber i2 This restricted space spray plug 22, of substantially the form shown in the drawing, with the square base portion 23, having the corners cut and tapered, as at 23, and with a neck portion 2 3,

outlet 20, discharge passageway out of the cylindrical. portion of spray nozzle. This discharge strikes the flaring discharge mouth l6, of lesser angle, and results in an eflicient shower.

A coiled spring 26 keeps such spray nozzle in its down position, with its base resting on the conical floor i9, at its corners, as indicated, whereby water flows past said spray plug through the spaces, 23', left by the straight sides of the base 23, as will be understood from the horizontal sectional view in Fig. 6. Said coiled spring 26 is shown, with its large end groove 26 in the top of the the insert, and its small end, of the spray plug 22, subseated in an annular cylindrical portion of anchored to the top 3 stantially as shown, around a small lug portion 21.

If any hard particle should lodge in this angular discharge passageway, at l9 and 20, Fig. 5, between the spray plug and the wall of the insert, it is only necessary to press the finger against the end of said spray plug to enlarge the outlet opening and the particle will be discharged. It will be understood that said spray plug 25 can be pushed into the cylindrical member 2|, as shown in Fig. 5, and thatwhen released, it will be returned to the position indicated in Fig. 3. 7

Thus I have provided a most efficient shower head or body into which can be inserted a plurality of spray nozzles, so positioned that the sprays discharged therefrom will overlap each other in a most effective manner to produce a most eiiicient shower.

I have also produced a self-contained spray nozzle, which can be used as an insert into most any kind of a shower head having a waterreceiving chamber therein, or it can be used as a single nozzle.

I have also provided a most simple means for releasing any hard particle which may become lodged in the discharge outlets, by simply pressing the spray plug inwardly and then allowing it to be returned to its normal position by the coiled spring 26' operating thereon.

I do not, therefore, limit the invention to the details of'construction and arrangement shown for explanatory purposes, except as I may be limited by the hereto appended claims, forming a part of this specification.

I claim:

1. The combination with a shower head having means for connecting it with a source of water supply and having a chamber therein to receive water from said source of supply, the ceiling of 4 said chamber being flat, the bottom of said head being parallel therewith and having a plurality of threaded openings therethrough, of a plurality of insertable cylindrical spray nozzles to be inserted in said openings, the upper ends of said cylindrical spray nozzles being positioned adjacent the ceilings of said chambers to form restricted openings as a trap for particles, means in said spray nozzles for giving form to the sprays discharged therefrom, said nozzles being posi tioned relative to each other to cause an overlapping of the sprays discharged therefrom, whereby to greatly increase the efficiency of the shower from said head.

2. A shower head with means for connecting it adjustably to a source of water supply, said head having a chamber therein with floor and ceiling, said floor having a plurality of threaded openings therethrough, and a plurality of separate unitary spray nozzles adapted to be screwed into said threaded openings, each having a cylindrical portion with its upper end adjacent the ceiling of said chamber to form a restricted opening into said spray nozzle, and means in said spray nozzles for giving conical form to the sprays discharged therefrom, said sprays being discharged in overlapping relationshlpwhereby to increase the efficiency of the shower from said shower head.
